Other claims from this paper (5)
- Observation FISH visualised Bretziella fagacearum ascospores on Carpophilus sayi collected from sporulating mats.
- Observation Bretziella fagacearum showed consistent localisation on terminal abdominal sternites of the vectors, and occasionally on mesoventral grooves, legs and antennae.
- Observation Bretziella fagacearum hyphae were predominantly in oak twig vessel elements and fibres, and occasionally in axial and ray parenchyma.
- Observation In infected petioles, hyphae occurred in xylem vessels, collenchyma, and parenchyma, beyond midrib tissues.
- Method / resource CLSM–FISH is established as a powerful visualisation tool for host–pathogen–vector interactions of oak wilt.
